[PATCH] tests: Use '.' and not 'source' which is a Bashism.

[Taylan Ulrich Bayırlı/Kammer]

I assume the test is supposed to run with any standards compliant shell
and not specifically GNU Bash:

Subject: [PATCH] tests: Use '.' and not 'source' which is a Bashism.

* tests/profiles.scm ("etc/profile"): Use '.' instead of 'source', since the
  latter is a Bashism and not necessarily supported by a standard shell.
